Slag and fly ash replace clay for cement production. 矿渣和粉煤灰替代粘土进行水泥生产。原料组分包括石灰石、石膏、粘土和铁粉等。在干法生产工艺中，除这些组分外，还包括掺入粉煤灰和矿渣等工业废渣。能源消耗包括各生产工序的电耗和煤耗，污染物则包括颗粒物、SO2、NOx和CO2等。 11 2004 This dataset describes the production of ordinary Portland cement with a strength class of 42.5MPa, using a dry process that incorporates mixed solid wastes, specifically slag and fly ash. Slag and fly ash are used as substitutes for clay in the cement production process. The described cement is applicable for general construction purposes including the construction of buildings, bridges, roads, and other infrastructure projects where high strength and durability are required. 该数据集描述了一种42.5MPa强度级别的普通硅酸盐水泥的生产过程，该过程采用了新型干法并掺入了混合固体废料，特别是矿渣和粉煤灰。矿渣和粉煤灰被用来替代传统的粘土原料。所描述的水泥适用于一般建设目的，包括建筑物、桥梁、道路以及其他基础设施项目，这些项目需要较高的强度和耐久性。 The study used 1kg of 42.5 grade Portland cement as the functional unit for evaluation. The scope of evaluation is defined as the in-plant production process of cement products and its surrounding environment. Among them, the in-plant production process refers to the entire production process in which raw materials undergo pretreatment, raw meal grinding, calcination, clinker mill, cement homogenization and other processes and finally become cement products. The surrounding environment of the cement production process refers to the input of external resources and energy and the emission of pollutants. 研究以1kg42.5等级硅酸盐水泥作为评价的功能单位。评价范围界定为水泥产品的厂内生产过程及其周边环境。其中，厂内生产过程是指原料依次经过预处理、生料粉磨、煅烧、熟料磨和水泥均化等工序最终成为水泥产品的生产全过程。水泥生产过程的周边环境是指外部资源和能源的投人和污染物的排放等。 Unit process, black box None 无 None 无 None 无 None 无 None 无 朱天乐, 何炜, 曾小岚, 黄新, & 马保国.

Users of this dataset should consider the inclusion of external resource input and pollutant emissions in their assessment. The dataset is based on a functional unit of 1kg of 42.5 grade Portland cement assessing the in-plant production process and its surrounding environment. Remember to account for the preprocessing of raw materials, raw meal grinding, calcination, clinker milling, and cement homogenization processes. The methodological applicability of using industrial by-products such as slag and fly ash in the input mix should be reflected accordingly. 使用此数据集的用户应在评估时考虑包括外部资源投入和污染物排放等因素。数据集基于1kg 42.5等级硅酸盐水泥的功能单位评估，涉及水泥产品厂内生产过程及其周边环境。用户需计入原料预处理、生料粉磨、煅烧、熟料磨和水泥均化等过程。在输入混合组分中使用矿渣和粉煤灰等工业副产品的方法应用适应性应得到相应的体现。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 #REF!, ysqsophia@gmail.com ysqsophia@gmail.com ysqsophia@gmail.com 2024-03-19T21:18:09+08:00 2024-04-20T14:40:33.972934+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=ecd82560-93f4-4dfa-a11a-89372efe82ea&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses limestone, crushed, for mill Input 1073.7 1073.7 Limestone 石灰石 gypsum stone (CaSO4-dihydrate) Input 51.1 51.1 Gupsum 石膏 iron, powder Input 28.5 28.5 Iron powder 铁粉 ash Input 98.0 98.0 Fly ash 粉煤灰 blast furnace slag Input 137.6 137.6 Blast furnace slag 矿渣 hard coal Input 100.957 100.957 Standard coal.
